ROTARY ENGINE.

Specification of Letters Patent.

llatented J an. S, 1918.

Application filed February 13, 1917. Serial No. 148,370.

T 0 all whom it may concern. Be it known that I, AxnL LiLL Ursr, a citizen of the United States, residin g at Mullan,

in the county of Shoshone and State of lidaho, have invented new and useful 1mprovements in Rotary Engines, of which the following is a specification.

This invention relates to engines, and

1 especially to engines of the non reciprocatin g or rotary type.

The object of the invention is to provide an engine of this class which is positive in operation, simple in construction and having the fewest possible number of parts in order to reduce the cost of construction and operation.

Another object of the invention is to provide an engine in which the force of the motive agent will act upon impact members always traveling in the same direction, in order to overcome loss of power common to engines of the reciprocating type.

A still further object of the invention is the provision of an engine of this class which is provided with novel impact members, which will be automatically moved to an in operative position. as they pass into the entrance of the impact chamber and will be automatically restored to an operative position on entrance into the said chamber.

With the above and other ob ects in view the invention consists of an engine provided with a compression chamber, said chamber having a restricted entrance, automatically operated impact members adapted to travel through said chamber and a flexible guiding and controlling element for said impact members, the said members being acted upon by the motive agent supplied to the chamber through an inlet port, the said chamber being further provided with an exhaust port controlled by the impact members.

In the drawings Figure 1 is a side elevation of an engine constructed in accordance with the invention;

Fig. 2 is a plan view of the same with the cover removed from the compression chamber and showing the wear plate of this chamber in position;

Fig. 3 is a similar view with this plate removed looking into the compression chamber;

Fig. 4. is a longitudinal sectional view through the engine complete;

Fi g. 5 is a transverse sectional view of the same; and

Fig. 6 is an enlarged detailed sectional view illustrating the mounting of the pivyoted impact members and the flexible guiding element therefor.

in the practical Oil'llDOClill'lOllll of the invention the same consists of a suitable base 1 provided with bearings and 3 to receive shafts 4-. and 5 respectively. Upon each of these shafts are mounted a pair of sprocket wheels 6, the said sprocket wheels supporting a chain 7. The shaft 4i is provided with a fly wheel 8, and. a pulley (not shown) may be provided upon either of the shafts 1 or 5 for transferring the power from the engine.

Mounted upon the frame of the engine between the sprocket wheels 6 is a compression chamber 9, the said chamber having formed in its side walls grooves 10 for the purpose of guiding the sprocket chains 7 there th rough.

Rods 11 connect each of the chains 7 and pivoted upon these rods are the impact members 12 preferably in the form of plates pivoted upon each side of the chains 7 within the same. As the guiding groove 10 is located centrally in the side walls of the impact chamber the members 12 extend upon either side of the chain, the combined area of the members being equal to the cross scctional area of the impact chamber, so that a pair of these oppositely extending members will form a traveling wall or divisionfor this chamber. The members 12 are normally held in position at right angles to the chain 7 by springs 13, the said springs being located upon the rods 11 and having their opposite ends bearing against the face of the impact members as shown iniFig. 5.

The compression chamber 9 is formed with a restrictive entrance 1 1, this entrance being provided with outwardly flared portions 15 for the purpose of automatically folding or moving the members 12 to an inoperative position before entering the impact chamber. This folded position of the impact members is against the action of the springs 13, so that as soon as these members are released the spring will automatically restore them to an operative position as will be apparent. In order that the releasing or restoring of the impact members to their operative position may be most effective, there is provided within the compression chamber 9 a projection 16, the said projection holding the members 12 in their folded position until after they have passed sulliciently far into the compression chamber to obtain the force of the motive agent used.

The motive agent is introduced into the chamber 9 through the inlet port 17 and drives the members 12' through the said chamber until they reach its open end, whereupon the motive agent is exhausted and the operation continued by the following impact members. The exhaust end 18 of the impact chamber is normally open and is adapted to be closed and controlled by means of the members 12, the passing of the said members from within the impact chamber serving to open the exhaust end or port 18. In this manner the entire dead charge of gas, steam or other motive agent is entirely removed. The surface of the chamber 9 which the free ends of the members 12 engage, is provided with wear plates 19, the said wear plates having a cut a 'ay portion 20 to provide for the inlet port. The plates 19 in addition to providing for the wear against the surface also provide a smooth tight joint between the free ends of the members 12 and the working surface of the chamber 9. Covers 21 are secured to each face of the chamber 9 by means of bolts 22 or other fastening devices, a suitable packing being placed beneath these covers to insure a tight joint. For the purpose of limiting the outward movement of the members 12 when acted upon by the motive agent, the said members are provided with pivoted links 24-, the said links being formed with slots 25, which take over pins 26 carried by the chain 7, these links being secured to the face of the plates 12 as at 28 and lying within the chains 7.

The engine above described provides a simple and efficient means for the manufacture of power and is capable of being operated by various motive agents, such as steam, compressed air, water, etc.

Various changes in the'form, proportion and minor details of construction may be made as will properly fall within the scope of the appended claims.

Having described the invention, what I claim, is:

1. An engine embodying a casing, a compressing chamber therein, one end of said chamber being closed to form a stationary abutment wall, the opposite end of the chamber being open tothe atmosphere, normally extended impact members mounted for movement through the compression chamber, a restricted passage formed in the closed end'of said chamber for the pars sage of the impact members in a folded position, a flared entrance to said passage for gradually folding said members for entrance therein, means for automatically restoring said impact members to an extended position upon entering the compression chamber and an inlet, port positioned between the stationary abutment wall and the fully extended position ofthe adjacent impact member.

An engine embodying a casing, a com pression chamber therein, one end of said chamber being closed to form a stationary abutment wall, the opposite end of the chamber being open to theatmosphere, normally extended foldable impact members mounted for passage through the compression chamber andmeans carried by the abutment wall and extending into the compression chamber for retarding the opening of the impact members until they have passed the inlet port.

3. An engine embodying a casing, a'comvpression chamber therein, one end of said chamber being closed to form a stationary abutment wall, the opposite end of the chamber bein 0 ien to the atmos )here normally extended foldable impact members mounted for movement through the compression chamber, a restricted passage formed in the closed end of said chamber for the passage of the impact members in a folded position, means for automatically restoring said impact members to an extended position upon entering'the compression chamber, an inlet port for said chamber located adjacent the restricted passage and parallel arms carried by the abutment wall. and extending into the compression chamber for retarding the opening of the impact members'until they have passed the inlet port. 7

In testimony whereof I affix my signature.
